Secondary impression was taken using selective pressure impression technique with special tray using low fusing impression compound and zinc oxide impression paste. This can give the impression that the material is ready for use when the inside might still be quite hard. A clinical review of spacer design for conventional complete denture (4) Similar to some others published articles, (10-12) our primary impression of filling defects in ERCP was common bile duct stones or sludge. Available in the form of sheets, cakes, discs and sticks. Two types of impression compounds are available - Type 1 which is low fusing with a fusion temperature of approximately. Provided are a binder resin composition for toner excellent in low-temperature fusing property, storage stability and durability, a toner for developing electrostatic images that contains the binder resin composition for toner, and a method for producing the binder resin composition for toner. Impression Compound Tracing Sticks is a Type 1 low fusing material primarily used for border extensions on impression trays. Low-fusing counterdies for measuring accuracy of dies or impression materials. w SOLOMON E G R 1973 used silicone material for complete denture impression – a high viscosity material for border molding and low viscosity material for secondary impression. 2 types of Impression Compounds. The composition varies from one product to another but an indication of typical composition is given in Table 17.1.

Available in Green primary impression with impression compound in a nonperforated stock tray; the borders are refined. Low-fusing. This compound is thermally reversible, rigid when cold, and plastic when heated to a few degrees above mouth temperature and hence termed as thermoplastic material. low fusing compound for border molding. efficiency, while Low fusing Impression Compound Type I a had the least efficiency amongst the three when used for the purpose of border molding. The water bath should be set at 110 degrees when using low fusing compound . In a survey of predoctoral clinical curriculum it was noted that 64% used low fusing compound for peripheral tracing.10 Impression compound was more frequently used in my study which is quite similar to the study in the … Mean border values obtained with all the three border molding materials (putty silicone: 22.774 sqmm, low fusing impression compound: 20.5007sqmm and pattern resin: 14.1266 sqmm.) The thermal conductivity of impression compound is very low, meaning that, on softening, the outside will always soften first. Border molding is done with low fusing compound. Impression Compound is a thermoplastic impression material available in cakes – for full or partial impressions – and sticks – for copper band impressions and for adding to the periphery of an impression tray. Low-fusing compound has a melting temperature of 60°C, according to the manufacturer. Final impression is made either using zinc oxide eugenol or with a medium viscosity elastomer. This is done by squirting ice water from a bulb syringe along the borders of the completed impression and over as much of the impression surface as possible. Always temper the compound in the water bath for 5 seconds before placing the heated compound in the mouth. Above 45°C and Type 2 which is high fusing with a fusion temperature of approximately above 70°C.
